These guys did their home-work and wrote good IO drivers too. I sold my Beagle Bone Black and bought this. It's stable, faster well designed, and has a working Ubuntu SD image on the internet. Some great pluses are: Video HDMI uses the standard size connector. Supports USB On The Go. Micro size SD cards, with latches that really hold it in, unlike some others! Fast speed, runs apache2 and php5 w/o problems. I even ran a few simple benchmarks with Raspberry Pi, BBBK and pcDuino. See them at www.marchdvd.com/pcduino/ This board is a keeper and when other projects arise, I may get another. Worth paying for something that works!
